It has been more than 40 years since the reform and opening up from 1978, China’s manufacturing industry has been developing rapidly, which needs a strong and independent manufacturing industry from the perspective of national living standards, economic development and national security. The emergence of the new industrial revolution is not only a challenge, but also a rare opportunity. China has entered the late stage of industrialization and is in a critical period of economic restructuring and upgrading. The new industrial revolution has promoted a large number of new technologies, new industries and new models, laid a technological and economic foundation for China’s industrial development, defined the future direction of development, providing an important opportunity for China to scientifically formulate industrial development strategy, accelerate economic transformation and upgrading, and grasp the initiative of development. Now let’s learn about the application of RFID technology in manufacturing industry.
RFID tags on production line can be automatically controlled and monitored by using RFID technology, which greatly improves the production speed and accuracy, work efficiency, production methods and saves costs. RFID tags can record process information and process operation information conveniently and accurately to meet flexible production requirements. It can improve productivity, production mode and save cost,using RFID technology to realize automatic control and monitor on production line
I.Demand Analysis of RFID in Manufacturing Industry
Therer are a lot of materials almost every month in manufacturing lines, production results and expectations are often affected by errors in delivery, production lines are often caused by human errors. But if the RFID tag is attached to the product material or product, which can automatically record the production information such as the quantity, specification, quality, time and person in charge of the product, instead of the traditional manual record; the production supervisor reads the product information at any time through the reader; other relevant personnel can timely grasp the production situation and adjust the production arrangement according to the situation; the information of purchase, production and storage is consistent and can be monitored in real time; Before materials and products leave the warehouse, the system will automatically record the information of entering and leaving the warehouse, and can track the location of the goods in real time.
RFID technology is used to name an ID to each part in manusfacturing process, in other words, the name of the part is in the information network. The production status and inventory situation are mapped to the information network, registered in the field central database, and transmitted to the information system through RFID technology. The application of RFID technology in production line monitoring can realize automatic control and detection and save cost. The RFID tag can uniquely identify every product. The application program records the raw material and source, production line location, production process and inventory status of each product, which provides an effective basis for enterprises to better manage production and adjust inventory.
II.Application Characteristics of RFID in Manufacturing Industry
1.Real-time data sharing
In the production process of manufacturing enterprises, it is very important that we get timely and accurate feedback information from production line. In the past, we can only record the faults manually while we are producing. After the production is completed, we can collect the information from each process, which is time-consuming and laborious, and sometimes can not be very accurate. Install RFID reading equipment in each process of production line, and place repeatable RFID tags on products or pallets. In this way, when the product passes through these nodes, the RFID reading and writing device can read the information in the label of the product or tray, and feedback the information to the backstage management system in real time, so that the manager can know the working condition of the production line in time.
2. Control standardized production
The information provided by RFID can be used to ensure the correct use of machine equipment, tools and components, so as to achieve paperless information transmission and reduce the waiting time for shutdown. Furthermore, when raw materials, parts and components pass through the production line, we can be carried out to ensure the reliability and high quality of production as we get the timely and accurate feedback of real-time control, modification and even reorganization of the production process
In the production line of implementing the RFID system, the product quality is tested the whole process. At the end of production or before acceptance of the product, the quality of the product must be clearly expressed with all previously collected data of the work piece. These informations can be easily achieved by using RFID tags, because the quality data obtained during the whole production process has gone down the production line with the product.
4.Application Principle of RFID in Production Line
At present, the production management system based on bar code makes all kinds of quality analysis and control easy to realize, and the bar code technology has its advantages and obvious disadvantages, such as easy to be polluted, to be damaged, close scanning distance, etc. The batch reading efficiency is not high, and can not meet the needs of fast and efficient. Using RFID tags, bar codes and sensors to collect real-time data from the production line and transmit the read data to the upper devices (controllers or computers) via the network (wired or wireless). However, as to manage loose sensors, a new management mechanism is needed, which can automatically discover and organize the feedback from the network. The method adopted is to deploy the RFID reader and establish the reader network connection to solve the problems of reader network planning, optimization and control. The RFID tag on the item, together with the RFID reader connected to the network, each recognition means a tracking of the item.
